In ''Heard it Through the Grapevine" Yoo Joon Sang put pressure on Ko Ah Sung's parents with money.
In the 6th episode of SBS Monday/Tuesday drama ''Heard it Through the Grapevine" broadcast on Mar. 10th, Han Jung Ho (played by Yoo Joon Sang) and Yeon Hee (played by Yoo Ho Jung) invited Suh Bom's parents Suh Hyung Shik (played by Jang Hyun Sung) and Kim Jin Ae (played by Yoon Bok In) to their house.
Jung Ho was worried that their future in-law counterparts who were poor would do something weird and crazy. Thus, he wanted to make a preemptive move. He invited the in-laws and treated them in the most polite way to show that he was part of the high class.
After this, Jung Ho and Yeon Hee showed their direct requests to Suh Bom. Jung Ho said, "This is a pity that it's a structural problem. I heard that your prior generations have all been self-made millionaires and that your brother too was a great employee" as he spoke of the family. This showed that he had done his background research and hinted that it was to make arrangements to give their daughter a permanent job at a company.
